degradation of water quality have emerged. There are two basic approaches to mitigate the effects of droughts: (i) to store maximum water for its subsequent use in the period of drought; and (ii) to manage the existing water resources (both surface and groundwater) efficiently. The existing limited water resources during drought could be managed by: (i) effective mass media campaign; (ii) improving water application and water use efficiencies by adopting high efficiency irrigation systems and using proper

Introduction According to studies of the Davao City Water District‚ 98 percent of the city’s drinking water is sourced from groundwater mainly from Talomo-Lipadas. This 38‚000-hectare watershed has an annual volume of water catch of 760 million cubic meters (MCM) or 2 MCM per day. It is one of the nine watersheds in the city that direly needs protection. In Davao City the main source of water supply is ground water. Hence‚ the city depends largely on the Mt. Talomo-Lipadas watershed. This

The results of this sampling program were used to determine the final location of the groundwater extraction wells. After that‚ URS initiated on-site construction activities in August 1999. They firstly uncovered seven dry wells approximately 3 m in diameter and 4.5 m deep which were abandoned before‚ as monitoring wells. Then three extraction

A watershed is a system of how water can get from one body of water to a larger body of water. Watersheds work by a simple concept‚ which is that water flows to the lowest point of a terrain due to gravity. The borders of a watershed are defined by hills or mountains‚ which create a natural divider‚ because water cannot flow up that surface. These are known as “watershed divides”. An example of a watershed is the Etobicoke River Watershed. Streams of water flow downward‚ to form larger streams of

Based on above analysis‚ scenario 1 was suggested for LH‚ WY and WQQ‚ scenario 2 was suggested for DK‚ and the basic scenario was suggested for HH during 2000-2010 (Table 7)‚ in order to ensure efficient and high-yield crop production without seriously decreasing the groundwater depth in a normal year and to save as much water as

only the broad theme of water scarcity - a problem with which I was not very familiar with. After much research‚ I learned we had a global groundwater problem‚ which also had local implications. I‚ then‚ presented‚ formally‚ my findings to other officers and members‚ and led challenging discussions about what role rights and responsibilities play in the groundwater issue. At one point‚ I realized how little my peers - engaged college students - knew about the theme; if that was true‚ maybe the general

water from under the ground. But‚ groundwater depletion is causing a lot of bad things to happen. It is making the layer of clay above collapse‚ when the clay collapses the dirt above gives way and sinks. This sinking causes sinkholes and is very dangerous. The sinking also damages pipes‚ buckles walls of irrigation canals‚ and cracks homes. Although the sinking is already a big enough threat the water in general could be dangerous. In some cases groundwater becomes contaminated‚ this occurs
