This research aims to study rain intensity which causes floods in Mueang Phetchaburi District. The analysis was based on six major flood incidents in Mueang Phetchaburi District during 2003-2016, daily rainfall data from 11 stations reported by Meteorological Department and the Royal Irrigation Department, daily runoff data from 6 stations reported by the Royal Irrigation Department in Phetchaburi watershed, and sea tide data from 1 station reported by Marine Department. The study found that rain intensity which causes flood in Mueang Phetchaburi District includes 1) rainfall accumulation over 100 mm in two days within Mueang Phetchaburi District or 2) rainfall over 100 mm per day above Mueang Phetchaburi District or rainfall accumulation over 200 mm in two days or 3) the amount of runoff was more than 150 cubic meters per second at B.10 streamflow station. It was also found that the highest sea tide level was more than 3.90 m. MSL. These are the factors affecting slower water flow into the sea resulting a longer flood in the area. When the situation arises, the people should be warned in order to be prepared for the coming flood. PubDate: 2021-06-21 Issue No:Vol. 17, No. 2 (2021)
Authors:กุลการ มงคลชูโชคทวี Kunlakan Mongkonchoochoktawee, จุฑารัตน์ ชมพันธุ์ Chutarat Chompunth Pages: 22 - 41 Abstract: The problem of Water Resources Allocation has been increased regularly from the past until present, causing environmental conflicts in the society. Meanwhile, public participation is considered as an important principle that can solve water resources management problem. The objectives of this study are to study public participation practice in water resources management; and, to propose guidelines for promoting public participation for sustainable water resources management. This study is a qualitative research. The literature review and semi-structured interview with stakeholders were applied to collect data. The result of the study found that most people in the affected area are given insufficient project information because the project developer only provided information to community leaders. As a result, most people were unable to access accurate information. The administration of the authority was top-down style. Thus, most people were not given enough opportunities to participate in Water Resources Management, therefore, public participation was at low level. For the guidelines to promote public participation, the project developer should provide information that is clear, and easy to access. The developer should give opportunities to all stakeholders to share their opinions and the authority should change the administration style from top-down to bottom-up. Finally, the developer should provide information that is accurate and open to public, as well as promoting a higher level of public participation that will lead to sustainable Water Resources Management.

Authors:คมวิทย์ ศิริธร Komwit Siritorn, อรรถพล นางแก้ว Attapon Nangkaew Pages: 42 - 59 Abstract: Presently, the typical tools using for white shrimp fishing are shrimp trap and floating trawl. Both of them can cause the economic losses due to the improper size of caught shrimps particularly via the shrimp trap. This significantly impacts on a huge reduction of shrimps in natural sources. Hence, the purposes of this study are to examine the economic losses and benefits of white shrimp fishing and to compare the effective usefulness of both fishing tools. The data have been collected through interviewing and field recording of caught shrimps in terms of quantity and average weight of caught shrimps in each round. Shrimp fishermen in Hat-Samran Sub-district, Hat-Samran District, Trang Province have been selected as purposive samples. The concept of opportunity costs, production costs, and returns have been adopted to measure the economic losses and benefits. The findings revealed that shrimp fishing by shrimp trap triggered to economic losses or opportunity costs of the improper size of shrimps fishing in value of 31,374.00 Baht/round, whilst those of the losses via floating trawls cost 24,975.00 Baht/round. When taking the production costs and returns into the consideration, it could be seen that shrimp fishing thru floating trawl was higher worthiness than that of shrimp trap. Therefore, policy makers who oversee the shrimp fishing in that area have to educate and notice fishermen the effectiveness and usefulness of shrimp fishing via floating trawls in order to replace shrimp trap by floating trawl and to obtain sustainable mode of shrimp fishing.

Soil samples were collected by using the Judgement/Biased sampling method from 77 retail shops and the amount of heavy metal was analyzed by the X-ray Fluorescence Spectrophotometry technique and Atomic Absorption Spectrophotometry (AAS). Independent Samples Test (t-test) was selected to compare statistical differences of heavy metal content in soil detected by both analytical methods. The results showed that there was no difference found for copper, lead, and zinc contents (statistical significance level of 0.05); but the analytical results of cadmium, nickel, manganese, and chromium were different (statistical significance level of 0.05). The correlation to arsenic could not be conducted because they were not detected. The risk assessment of exposure to heavy metal contamination resulting from electrical and electronic equipment sorting and detected by both analytical methods found no harmful health effect. However, retail shop owners should be well aware of the dangers and request staff to wear personal protective gear during working hours. In addition, Daeng Yai Subdistrict Administrative Organization should provide a proper purchasing procedure and handling method for retail shop owners on a regular basis.

Authors:วศิน พิพัฒนฉัตร Vasin Pipattanachat Pages: 116 - 129 Abstract: In Thailand, the problem on the telecommunication towers that are installed near residential communities without the consent of the people in the area has appeared and brings about an unsuitable environment to people living next to or near the towers. They currently generate problems in mental health and concerns on the hazards to the physical health in the future. Moreover, the stability of the tower is another problem that can occur in the event of thunderstorm. However, by considering the importance of the towers installation, the existence of telecommunication towers near the community would favorably result in better efficiency of communication as well as accessing information with ease. Therefore, it can be said that telecommunication tower setup is an issue related to the weight of benefits between the public interest and the private loss. The process of setting up telecommunication towers is subject to a separate license. However, the link between the governments agencies and people in the area is to conduct the public hearing in the community. The doubt on the effect of the telecommunication towers installation usually derived from the lack of public hearing that consequently causes incomprehension of the people living in the adjacent area or near the place of installation. Eventually, the problems tend to be led to the litigation as appeared in many regions of Thailand. PubDate: 2021-12-13 Issue No:Vol. 17, No. 2 (2021)
