Maharashtra SSC Water Security Grade study plan

Map Maharashtra's five physiographic-cum-drainage divisions (Konkan coast, Western Ghats crest, Deccan plateau, Tapi-Purna trough, eastern Vidarbha) and label the major river basins falling in each

Compare the west-flowing and east-flowing drainage systems by rainfall share, catchment area and utilisable yield, and explain why most of the state's water is generated on roughly a tenth of its area

Quantify the rainfall gradient from the Ghats (over 2,500 mm) to the rain-shadow interior (under 600 mm) and connect it to the state's recurring spatial water imbalance

Distinguish between average annual availability, dependable (75 percent) yield and per-capita water availability, and state which figure planning actually uses

Explain the hydrological cycle components in a Maharashtra context, including monsoon onset and withdrawal, evapotranspiration losses and the role of the Ghats in orographic rainfall

Trace how a raindrop on a Deccan slope becomes surface runoff, soil moisture, interflow or groundwater, and identify which pathway dominates on hard basalt versus alluvium

Delineate a watershed and its sub-watersheds on a sample toposheet and rank the ridge, slope and drainage-order features that control its response

Describe catchment treatment measures (contour trenches, check dams, afforestation, gully plugging) and predict their effect on peak flow and base flow

Compute a simple water balance for a small catchment using rainfall, runoff and storage change figures

Identify the main drinking-water contaminants of concern in Maharashtra (fluoride, nitrate, salinity, iron, arsenic in limited pockets, microbial load) and state the health effect and vulnerable districts for each

Explain the BIS permissible limits for key parameters and interpret a supplied water-quality test report against them

Describe the faecal-oral transmission route and how bacteriological contamination of a dug well or tanker supply produces waterborne outbreaks

Outline the standard field and laboratory tests (pH, turbidity, residual chlorine, MPN or H2S vial, fluoride and nitrate kits) and what each detects

Plan a household-level response to a contaminated source: boiling, chlorination dose, safe storage and when to switch sources

Describe the rural and urban drinking water supply chain in Maharashtra from source to household tap, including the roles of the state water supply and sanitation department, zilla parishad and municipal body

Explain the Jal Jeevan Mission household tap connection norms and the meaning of 'functional household tap connection'

Compare sanitation options (twin-pit toilet, septic tank, community toilet, sewage treatment) and identify the stages of faecal sludge management

Apply the F-diagram to block each contamination route and design a hygiene behaviour package for a village or school

Calculate a residual chlorine dose and interpret a turbidity reading against treatment requirements

Classify Maharashtra's irrigation sources (canal, lift, well and borewell) and estimate the share of irrigated area served by groundwater

Explain the mismatch between large canal commands and their low water-use efficiency, and describe the causes of waterlogging and secondary salinisation

Compare flood, furrow, sprinkler and drip irrigation by application efficiency and identify crops where drip pays back fastest

Select crops and cropping patterns suited to scarce water using the concept of crop water productivity, and justify a shift away from water-intensive crops in a rain-shadow district

Compute crop water productivity for two competing crops from supplied yield and water-use figures and recommend the better choice

Distinguish in-situ soil moisture conservation from ex-situ storage and recharge, and match each technique to a slope and soil type

Design a rainwater harvesting system for a roof of known area and rainfall, calculating harvestable volume and tank size

Explain how percolation tanks, recharge shafts, farm ponds, check dams and continuous contour trenches recharge groundwater, and state the site conditions each needs

Evaluate the risks of recharge (contamination, hard-rock siting failure, over-extraction) and describe how to monitor whether recharge is working

Interpret groundwater level data from observation wells to judge whether a recharge intervention has had an effect

Outline the constitutional and legal framework governing water in India and Maharashtra, including water as a state subject, the riparian principle and the doctrine of public trust

Describe the mandate of the key institutions: water resources department, Maharashtra Water Resources Regulatory Authority, groundwater authority, pollution control board and local bodies

Explain the Maharashtra Groundwater (Development and Management) Act's approach to notified areas and how it differs from open-access extraction

Identify the main inter-state and intra-state water-sharing disputes affecting Maharashtra and the principles invoked to settle them

Design a community mobilisation and behaviour-change campaign for a water issue, using social norms, trusted messengers and feedback rather than only awareness messaging

Map the roles of gram sabha, water user associations and self-help groups in operating and maintaining a local water scheme

Classify Maharashtra's water-related hazards (drought, flood, heavy rainfall, dam-related risk, hailstorm and unseasonal rain) and identify the districts and seasons most exposed to each

Explain how climate change is projected to alter monsoon variability, extreme rainfall and drought frequency in the Deccan region, and separate confident projections from uncertain ones

Describe structural and non-structural adaptation measures, including flood forecasting, reservoir rule curves, drought contingency planning and crop diversification

Prepare a household and community disaster preparedness checklist for both flood and drought scenarios

Consolidate the whole syllabus into a revision sheet linking availability, catchment, quality, WASH, irrigation, conservation, governance and disaster risk
