Analysis of Double Meridian Distance for a Closed Traverse Area towards Developing a Contour Map and Land Title

This research aimed to analyze double meridian distance for a closed traverse area in developing a land title for a propose gymnasium in Qassim University. Theodolite, leveling rod and steel tape plays an important role in measuring elevations, bearings and distances of the boundaries of a lot. Contour map is necessary to determine the traces of level surfaces of successive elevation. This will enable to identify the type of contour map and type of contour lines necessary for this project. Corel draw software is used to draw contour map and guide to interpret the significance of the variables. It is essential to check the error of closure for interior angles and for both latitude and departure before applying the Double Meridian Distance (DMD) method to obtain the total area of the lot. Technical descriptions of the land such as distance, bearing, boundaries and area are necessary to visualize the shape & exact location of the land. Developing a land title will be obtained using the technical descriptions of the lot in preparation for the type of gymnasium necessary for Qassim University

Natural Flood Management: A restatement of the Natural Science Evidence

Flood events often have severe socio-economic impacts, such as loss of lives and livelihoods, food, water and energy scarcity, and adverse impacts on human health and the environment. As far as feasible, human interference into the processes of nature should be reversed, compensated and, in the future, prevented. This study explores the possible solutions for the drainage system to ensure peak performance that might be adopted in España Boulevard, Manila. It aims to describe the wastewater management system to prevent and protect the adverse impact of flood events on human health and safety, on valuable goods and property, and on the aquatic and terrestrial environment

Environmental Flood Protection Dikes

Flooding is a natural event that replenishes the groundwater and revitalizes the soil through the deposit of sediments. However, when communities settle within floodplains, flooding can cause adverse social, economic and environmental impacts. Flood protection works, such as dikes, can further reduce flood risk. These structures particularly relevant in protecting historic communities that were settled before floodplain management policies were implemented. However, it is technically and economically impossible to completely eliminate flood risk with dikes. During severe floods, dike failures may occur due to erosion, overtopping or seepage. This study predicts that dike construction may lead to water level lowering for in-bank flows and to water level increases for out-of-bank (flood) flows. This confirms that, in principle, the existing Pampanga dike and specifically on the construction of Taguig City dike along the Laguna Lake may have contributed to the observed flood water level trends in the Metro Manila

Performance of Community Water Supply Management towards Designing Water Safety Plan

Potable water is a commodity and basic necessity of life for which metropolitan areas and adjacent areas are to pay. Water from Manila Waterworks and Sewerage System (MWSS) has also become a problem considering the low water supply coming from their sources. Because of El Nino phenomena and other problems of the water system, rationing Metro Manila was implemented. This descriptive study aimed to assess the performance and effectiveness of community water supply management in terms of the quality of water such taste, odor, color, sediments, service and cost and design water safety plan for the community. Purposive sampling was used to determine the participation of the knowledgeable homeowners of Karangalan Village in the province of Rizal. Some interesting insights of the study are: Potable water is the water delivered to the homeowners. However, there are sediments and brownish color observed in the water due to pipe corrosion. In terms of service, the performance of the water system delivered to the homeowners is acceptable based on the volume delivery, accessibility, availability, promptness, and reliability. Homeowners who use potable water are satisfied in terms of its efficiency, effectiveness, user-friendly, promptness and expandability. Water safety plan is an integral part of the whole planning process and helps improve the management of Karangalan village water supply and may be undertaken or updated at any tim
