Abstract

With the continuous climate change we are experiencing; extreme heat, drought, and declining water supplies that affect our rain fed and irrigation systems resulting to a higher demand for water for evaporation and evapotranspiration by crops which lead to more frequent soil moisture deficit which is unavoidable and there are still other factors that contributes to water head loss. This make it necessary to find out novel ways to resolve the issues regarding irrigation management. Though there are many existing innovative water management ideas available out there, but it takes to shed huge amounts of government funds to implement. This study consists of designing a water-recycle model to efficiently use the limited water supply and further attain to serve the total surface area of irrigated rice. The proposed design uses a renewable energy that pumps out water from the catch basin back to its water source, this method entirety use the most out of the water supply to lessen water wastage and water shortage and to maximize water saving in the area.

Highlights

As the demand of water arises to irrigate agricultural lands in depletes over 70% of the total developed water supplies of the the Philippines, one of the major issues being confronted is world
The Model of Water Cycle can retrieve the water loss caused by seepage, drainage and percolation back to the ground surface for irrigation
By constructing this renewable energy powered pump in particular spots of the service area of the reservoir as shown in Figure 2, this will act as the new water source for rice fields and other crops especially in situations where the water in reservoir is insufficient to reach the tail ends portion of irrigation canals and distant rice fields of the total service area

Summary

Introduction

As the demand of water arises to irrigate agricultural lands in depletes over 70% of the total developed water supplies of the the Philippines, one of the major issues being confronted is world. Atmosphere because of evaporation from top surface areas, or Though the losses from these factors can be reduced by evapotranspiration from crops, or both. The part of applying concrete lining to the canals, but these costs millions the diverted water that has not evaporated drains to surface or of pesos to construct and implement. Common water saving practices is by using a concrete as aimed towards the highest satisfaction in the improvement of lining material for the full section and at the sides of the canal. The conveyance loss of the canal decreased from 2mm / day finding innovative ways on how to de-escalate the wastage of to 0mm / day, and the amount of silt deposition was water during irrigation. The quantity of seepage losses was model on how to entirety use the most out of the limited water decreased significantly. The quantity of seepage losses was model on how to entirety use the most out of the limited water decreased significantly. (Facon, 1997)
