      Abstract: This study compares the capability of simple data-driven and process-driven models to simulate daily discharge in a snow dominated semi-arid watershed in relation to its hydro-meteorological characteristics. M5 model tree was considered for daily discharge simulation of Taleghan watershed in north of Iran, and the results were compared with those of IHACRES and HSPF models. Results showed that with the same meteorological input data, the HSPF model performed best in predicting the daily runoff followed by the IHACRES model. M5 model overestimated the daily runoff in low flow season (May-December) as the water required to fill the watershed storage capacity was not considered by the model. Using the stream discharge of the prior day (Q<SUB align="right">t-1) as additional input to the M5 model resulted in much improved simulation of daily discharge (RMSE = 3.55, NSE = 0.94, KGE = 0.96).

      Abstract: This paper explains a procedure based on the master recession curve (MRC) for hydrograph separation into individual flow components, using the recession constant K. To evaluate the performance of this computational technique, the results of the baseflow component were compared to the baseflow component obtained from the recursive digital filter (RDF) method. The study has revealed that the results of baseflow achieved by both methods show similarity to a great extent, and the baseflow values agree better with (R2 > 0.77). Moreover, automated baseflow separation underestimates the simulated baseflow from RDF method by as much as 2.35%, or overestimates it by up to 23.55%, during rainfall. These methods were applied to a set of hydrometric measures in the Mellah catchment, Algeria. The results proved that the proposed method gives a better estimate of flow components.

  • Preliminary investigation on historical flood events using the HEC-HMS

      Abstract: Investigation on historical flood events in river catchment requires a proper estimation of discharge, that can achieve by developing hydrological modelling of the catchment. However, understanding the complex relationships between rainfall and runoff process is a complex task, and hydrologic models should be well-calibrated to make the application of the model effective. In this study, Hydrologic Engineering Center-hydrologic modelling system (HEC-HMS) has been developed for several sub-catchments in Kelantan River, Malaysia, for prediction of its hydrologic response and flood events for several return periods. The results are indicating the good performance of the HEC-HMS model for discharge simulation, in which the correlation coefficient (r) has been found to range from 0.64-0.98 and 0.75-0.95 during the calibration and validation periods, respectively. The study also shows that the major floods in the Kelantan River catchment have been in line with the 50-year ARI design flood that been simulated by the model. The proposed HEC-HMS model could be beneficial to the studied catchment in terms of preparing a comprehensive guideline of a risk for the existing and future flood problems.

      Abstract: This study presents the modelling of the transient thermal transfer of conduction coupled by convection in ACF, in order to simulate temperatures using Fluent software, for two sites: The first is Ghrib dam with a raw ACF, whose data is used to validate the model. The second site is Bouhnifia dam; on its ACF three cases are simulated: the first case is a raw ACF to determine the temperature distribution, the second case is a ACF protected by a 12 cm thick reinforced concrete layer, and the third case is a ACF protected by a 12 cm thick porous concrete layer. For the first case, the modelling only concerns conduction, whereas for protected cases a convection heat transfer with a convection coefficient of 20 W/m<SUP align="right">2</SUP>K is added. The modelling of the different cases is carried out for summer and winter periods, then a comparative study between the different cases, to determine which material has the power to better cool the ACF.

  • Determining the seasonal relationships between upstream flows and channel
           transmission losses along a dryland river reach

      Abstract: River transmission loss is the reduced amount of flow at downstream locations along a channel due to infiltration into the riverbed and riverbank, evaporation from water surface, transpiration by riparian vegetation and, temporary storage in the river and flood plains. Transmission losses reduce flood stage, recharge local and regional aquifers and, are main sources of groundwater recharge in dryland areas. This study determines the seasonal relationships between upstream flows and channel transmission losses along a river reach in Runde River catchment in Zimbabwe. Using regression equations, channel transmission loss volumes were modelled as the response variables while upstream flow volumes were the predictor variables. The study shows significant (p = 0.000) positive linear relationships between reach upstream flow and transmission loss during the cool, hot and rainy seasons. Also, during the post rainy season, a significant (p = 0.000) power relationship exist between reach upstream flow and transmission loss. This simple approach helps to understand water balances and transmission losses in data scarce dryland river systems.

  • Effect on sediment yield due to change in land use land cover and
           construction of hydraulic structures

      Abstract: Estimates of sediment yield from the basin are required for water resource management planning. The effect on hydrology and sediment yields of land use variations is examined in the Banzar River Basin, part of the Upper Narmada River, using the soil and water assessment tool (SWAT). The results specify that the increase in agricultural land and water bodies has resulted in deforestation, causing a decrease in sediment yield. The land use land cover (LULC) changes and the construction of hydraulic structures that impact hydrological processes were studied in this research. It was observed that in 30 years, 23% of forest land had been reduced to agricultural, commercial, residential, and water bodies. Hydraulic structure construction reduces sedimentation in the upstream area but increases sedimentation in the downstream zone. Therefore, a change in land use pattern is a long-term solution for a reduction in sediments yield.

  • Investigation on vertical wall abutment scour under steady and unsteady
           flow in compound channels

      Abstract: The depth of local scouring in a vertical wall abutment in a compound channel was investigated. Steady and unsteady tests were carried out for different lengths of abutments. For steady tests, the time evolution of scour depth and scour hole geometry was determined for different flow conditions. The experiments revealed that the more is the flow intensity and abutment length, the more are the scour depth and their ultimate values. Finally, a dimensionless equation that correspond the evolution of scour depth to the flow intensity and the abutment length was proposed. For unsteady flow, a symmetric hydrograph was applied and scour depth evolutions was determined. By stepping hydrograph, successive scour depths were obtained by using steady flow estimation during each step. The results calculated from the stepped hydrograph were almost identical to the results measured from the flood hydrograph.
