How the Engineering Works

Chicka Roads deploys a three-stage hydraulic calculation engine specifically calibrated for small-stream installations between 0.5m and 300m of gross head. The system starts with survey sheet levelling where you record station elevations using chainage references from intake to tailrace.

Flow gauging operates through stage-discharge relationships tracked over time. The platform builds a duration curve showing what percentage of the year each flow rate occurs, then calculates your design flow at the turbine efficiency threshold. Every reading updates the annual profile automatically.

Runner matching uses logarithmic head-flow diagrams with overlapping operational zones for nine turbine types. When you position your site conditions on the chart, the system highlights compatible wheels and calculates net power after accounting for pipe friction, bends, valves, and trash rack losses across your specific reach configuration.

Core Engineering Features

Multi-Station Levelling

Document intake weirs, forebays, track crossings, and powerhouse positions with ordnance level precision. Each station stores name, chainage, elevation, and site notes. Calculate gross head automatically from elevation differentials.

Pipe Reach Calculator

Configure every segment between stations with material selection across PE, uPVC, Steel, Iron, and GRP. Enter bore diameter, length, number of bends, valves, and trash rack presence. System computes velocity, head loss per 100m, and total reach loss using Hazen-Williams coefficients.

Flow Gauging System

Build stage-discharge curves from board readings over the gauged year. Each entry records date, staff gauge height, calculated flow, and conditions. Monthly maximum flow visualization shows seasonal patterns against annual design target.

Duration Curve Analysis

Interactive graph plots available flow against time percentage using logarithmic scales. Crosshair cursor reads exact values at any percentile. Design flow marker shows your selected operating point for turbine sizing across the installation's expected runtime.

Nine Runner Database

Compare Overshot, Breastshot, Drum cage, Spiral case, and five additional turbine architectures. Each wheel displays efficiency percentage, net power output at your conditions, and flow availability across your gauged year profile.

Head-Flow Matching

Logarithmic chart displays operational zones as overlapping rectangles for each runner type. Your site conditions appear as cyan crosshair showing exact head and design flow. Shaded zones indicate compatible turbines with detailed performance breakdowns below.

Technical Operation Breakdown

Survey Workflow

  • Create new site with project name and location reference
  • Add stations sequentially from intake to powerhouse outlet
  • Record chainage distance from reference point zero
  • Enter ordnance level elevation for each station position
  • Attach descriptive notes about site conditions and structures
  • Define pipe reaches between consecutive stations with material specs
  • System calculates gross head from elevation data automatically

Flow Measurement Protocol

  • Install staff gauge at intake or control point
  • Record stage height readings during varied flow conditions
  • Enter date, board measurement, and observed flow rate
  • Build discharge relationship over minimum six-month period
  • Platform generates duration curve from compiled measurements
  • Select design flow percentile based on turbine type and economics
  • Monthly bar chart tracks largest gauged flows against annual target

Runner Selection Process

  • Input net head after all pipe losses subtracted from gross
  • Confirm design flow rate at selected duration percentile
  • View head-flow chart with nine turbine operational zones
