Our investigations center around three different RWH structures: a set of interlinked ponds and a check dam near Jaipur as well as one sand dam located near Jodhpur. 4 Work Packages (WPs) have been designed to achieve the project objectives namely;
Fundamental geological and hydrogeological parameters - monitoring water quality used for recharge and groundwater in the vicinity of MAR schemes. Groundwater levels measurements, monitoring climatic parameters, infiltration tests to assess the efficiency of the structure, pumping tests, mineral characteristics of the aquifer material.
Tracer tests - quantify the proportion of artificially recharged groundwater in wells located near rainwater harvesting structures
User surveys - assess how the communities use water for drinking and productive activities and how water is governed locally, including how decisions are made about the location and design of MAR structures
Water and soil quality analysis along with sanitary surveys - Assess quality of the rainwater and groundwater, surface water bodies and from abstraction points used by the local community. Vertical aquifer profiling. Sanitary surveys to assess the impact of any contamination due to poorly constructed wells and boreholes
DOM characterisation - application of F-EEM techniques for reliable and fast determination of dissolved organic matter as well as trace pollutants in harvested water and aquifer materials.
Column experiments - hydraulic parameters of the aquifer material and transport, interactions and fate of established and emerging contaminants during MAR with rainwater.
Subcatchment model - groundwater quality modelling and model the possible changes in fluoride concentration
Individual MAR structure models - quantify contaminant retention in MAR structures
Embedding findings with project partners - Embedding findings with project partners which include NGOs and officials of the Rajasthan Ground Water Department
Global dissemination of findings - Communities such as engineers who implement water supply systems, hydrologists and hydrogeologists, as well as chemists
Local dissemination of findings - Local dissemination of findings explaining the findings of the research in local languages.
