TNC Architects delivers accurate hydrological surveys — catchment analysis, drainage studies, flood zone mapping and water resource assessment — for residential sites, agricultural land, infrastructure projects and PHD submissions across Ajmer and Rajasthan.
A hydrological survey is far more than a drainage plan — it is a complete picture of how water moves across, through and under your site. Catchment boundaries, runoff volumes, seasonal flood extents, infiltration rates and groundwater depths are all measured, analysed and documented in a report that protects your project from water-related risk.
TNC Architects conducts hydrological surveys for residential plots, agricultural land, roads, irrigation systems and PHD-submission projects — delivering AutoCAD drainage plans, catchment maps and signed hydrological reports accepted by municipal and government authorities across Rajasthan.
Delineation of watershed boundaries and sub-catchments — calculating runoff volumes, time of concentration and peak flow rates for drainage design.
Site and regional drainage analysis — existing drain capacity, overland flow paths, drain gradients and outfall positions mapped for design or approval.
Identification of flood-prone areas using terrain data and historical rainfall records — flood extent maps produced for 10-, 25- and 100-year return periods.
Groundwater depth and seasonal variation assessment — borehole log analysis, water table mapping and groundwater potential zones identified for the site.
Irrigation channel surveys for agricultural land — gradient analysis, command area mapping, water distribution design and flow capacity calculations.
Rooftop and surface runoff harvesting surveys — collection volume calculations, storage tank sizing and recharge pit design for farm and institutional projects.
Public Health Department hydrological reports — prepared to PHD specification with discharge calculations, flow data and signed certification for submission.
Rainfall-runoff modelling for site planning — peak flow estimates, storm return period analysis and stormwater management recommendations.
Water-related construction failures — flooded basements, eroded foundations, blocked drains — almost always stem from insufficient pre-design hydrological data. TNC Architects surveys every site's drainage behaviour, catchment flow and groundwater condition before a single design decision is made — eliminating costly surprises during and after construction.
On-site water level readings, flow measurements, soil infiltration tests and drain surveys — all data collected at source for accurate hydrological modelling.
AutoCAD catchment maps, drainage layout plans and flood extent drawings — produced to engineering specification and issued as editable .dwg files with PDFs.
Certified hydrological report with rainfall analysis, runoff calculations, flood risk assessment and surveyor's signature — accepted by PHD and municipal authorities.
Rajasthan's terrain varies enormously — from flash-flood-prone catchments near the Aravalli hills to flat, slow-draining plains in the Thar region. TNC Architects applies the right instruments and methodology for each site type, ensuring drainage calculations are accurate whether the project is a single house plot or a multi-hectare infrastructure scheme.
Current metering, flume gauging and staff gauge readings used to measure stream flow and water levels — forming the base data for all hydrological calculations.
IMD rainfall records, IDF curves and intensity-duration-frequency analysis used to calculate design storm events — from 10-year to 100-year return periods.
All hydrological data processed and issued as AutoCAD drainage drawings, catchment maps, PDF reports and a signed hydrological assessment within the agreed programme.
Site visited to assess terrain, drainage paths, existing watercourses, catchment area extent and flood vulnerability before fieldwork begins.
Flow gauging, water level readings, drain surveys, soil infiltration tests and catchment boundary mapping carried out across the full site.
Rainfall data, runoff calculations and flood modelling completed — catchment maps, drainage layout and flood extent drawings produced in AutoCAD.
Signed hydrological report, AutoCAD .dwg drawings and PDF files issued to client and project team — ready for PHD and municipal authority submission.
On-site flow gauging, water level measurement and soil testing — all hydrological data collected directly from the site, not estimated from regional averages.
All catchment maps and drainage drawings delivered as editable AutoCAD files — architects, engineers and consultants can use them directly without redrawing.
Rajasthan's flash-flood zones, seasonal drainage patterns and regional benchmark data known since 2021 — no generic national averages applied to site-specific problems.
TNC Architects is both hydrological surveyor and design architect — water data flows directly into drainage design, floor level setting and site planning without any handover gap.
