Gabrielle Simard-Moore 11.5 Paradox of Safe Yield Safe yield was originally defined as the amount of water that could be developed from a ground water reservoir without depletion of its reserves. Over time the definition has changed as economics‚ protection of ground water‚ and environmental affects have been considered in this concept as well. So‚ safe yield is now defined as the amount of naturally occurring ground water that can be taken from an aquifer on a regular basis‚ economically and

Table (Figure 4.1) and graphs (Figure 4.2 and 4.3) clearly depict that the amount of moisture in the soil on the south facing slope is much higher than that of the north facing slope. On average‚ the south facing slope contains 3.5 units of water while the north facing slope only contains 1.3 units of water in its soil. Therefore the amount of moisture in the soil on the south facing slope is signficantly more that of the north facing slope. As can be seen in Figure 4.1‚ all 10 sites have lower soil

Wetlands span the surface or sub-surface interface‚ storing water in various times as groundwater‚ soil moisture and surface water. They are vital ecosystems that support wildlife and perform valuable ecosystem services‚ such as flood protection and water cleansing. They also provide livelihoods for millions of people who live within and around them. For example‚ the Inner Niger River Delta in the Western Sahel zone supports more than a million people who make their living as fishermen‚ cattle breeders

RAIN WATER HARVESTING INTRODUCTION 1. Urban centres in India are facing an ironical situation today.

In parts of the rural areas of India‚ floodwater quickly flows to the rivers‚ which then dry up soon after the rains stop. If this water can be held back‚ it can seep into the ground and recharge the groundwater supply. This has become a very popular method of conserving water especially in the urban areas. Rainwater harvesting essentially means collecting rainwater

I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth
