To provide the background hydrological information for the assessment of environmental flow requirements at four selected ‘Environmental Flow’ sites, a hydrological model was set up to simulate the catchment in the present state (with water regulation  infrastructure) and to generate the natural flows (without water regulation infrastructure).

Agriculture is the main occupation of the tribe and they have a unique way of knowing plantation season for different crops by observing the flowering of some plants. The indicator plants are peach, wild cherry, camel foot and dancing girl.

This paper published in the Indian Journal of Traditional Knowledge highlights the findings of a study that correlates the indigenous knowledge and scientific knowledge in assessing the nutrient availability status of agricultural soil as practised by the Nyishi tribes who use visual properties such as colour, texture and topographic positioning of land/terrain.

This paper published in the Indian Journal of Traditional Knowledge makes an attempt to record the fisheries related indigenous technological knowledge in terms of fishing crafts and gears used in river Krishna.

This manual on the Eldis site published by OXFAM provides guidance to public health promoters, water and sanitation engineers, project co-ordinators

Human faeces and urine (toilet manure) are a serious waste disposal problem especially in areas with high human population density. At the same time they are rich in nutrients that are essential to plants.

This presentation by Sekhar Raghavan, Director, Rain Centre, Chennai, India highlights the experiences and the challenges faced by Rain Centre in introducing ecological sanitation in the coastal town of Kovalam near Chennai, Tamil Nadu, India along with Coastal and Rural development Trust (CRDT), a small non profit centre based in Kovalam .

The coastal town of Kovalam was selected as a case because of its peculiar situation with its location in a fast developing  peri-urban area in proximity to Chennai city characterised by good groundwater situation, adequate land and housing facilities, but with a glaring and urgent need and demand for toilets.

This paper in the Journal of Earth System Science deals with a study by National Institute of Oceanography (NIO), Goa to investigate the influence of monsoonal rainfall on hydrographic conditions in the Mandovi River of India. The study was undertaken at a location approximately 2 km upstream of the mouth of the estuary.

This paper in Journal of Earth System Science deals with paleochannel and paleohydrology of the Middle Siwalik (Pliocene) fluvial system in Northern India. In recent years, fluvial sedimentologists have carried out numerous studies to estimate quantitative hydrodynamics of ancient fluvial systems, particularly, their morphology and hydrology. The methods for reconstructing the morphology and hydrology employ either several groups of empirical relationships derived from modern fluvial environments or dynamic models of fluvial flow and sediment transports in alluvial reaches.
