Question

Can you please suggest me a literature on "Conservation or harvesting of water in a hilly region where there is no access to ground water due to the altitude".

And a suggested list of technology to solve the above problems.

Answer 1

The reservoir system at the study site consisted of a cross dam, spillway, gate valve, pump, storage tank, water conveying channel, pipe networking and risers. A cross dam between two hills collects surface runoff during rainy season from June to November.
The overland runoff part of rainfall was stored in the reservoir. The runoff water was not treated because it was enriched with wash load including silts and clay particles
and suitable for irrigation.
In the hills and mountainous regions where there are plenty of streams, simple engineering structures were used to divert the water into channels that fed the fields. The structures became more sophisticated and much bigger when the streams turned to rivers.
The economic benefit of the system was calculated based on gross benefits obtained from different outputs of the cultivated area and cost for the inputs of the system. Benefit–cost ratio was calculated on the basis of annual benefit and cost of the system. The items included for benefit calculation were the outputs for agronomic and horticultural crops. For cost calculation the items were labour, seed/seedling, fertilizer, manure and irrigation. The cost of the items was calculated based on the prevailing rates in the area.

If you have any queries plz ask in comments section. Thanks
