Catchment Topography
Six River Trent stations are positioned left-to-right via dedicated
StereoPannerNodes from Stoke-on-Trent headwaters (53 km²) to North Muskham tidal gateway (8,231 km²).
Interactive Hydrological Sonification Visualizer
Catchment Station Mixer (Headwaters −0.90 L → Estuary +0.90 R)
Each gauge’s waterFlow is independently normalized (0.0 → 1.0) so flashy upland tributaries carry equal sonic weight to the lower River Trent. Solo or mute any station.

Micro-Jittered Droplet Plucks
Every 0.2 mm tipping-bucket increment schedules micro-jittered C-Lydian bubble-sine & bandpass-noise droplets panned to that station’s exact river coordinate.
Bowed Cello Open Fifths
Detuned sawtooth + woody triangle cello pads voiced in ascending fifths (C2 · G2 · D3 · A3 · E4 · B4) open their low-pass cutoff, swell gain, and deepen vibrato as the flood crest passes downstream.
Continuous Water-Quality Sonde Telemetry · Silverdale Brook
30-minute sub-daily dissolved oxygen, temperature, and suspended-solids turbidity across a 30-day summer window with convective storm flushes.
How It Sounds · Mode 02 Mapping Legend
Fundamental Oscillator Pitch
Warm detuned sawtooth, sub-sine, and fifth oscillators glide continuously across a full octave (98 Hz G2 at cool dawn to 196 Hz G3 in afternoon warmth).
Resonant “Breathing” Wah Sweep
Aquatic plants exhale O₂ in sunlight and respire at night; this 24-hour sine wave sweeps a high-Q resonant low-pass + vowel-formant filter (190 Hz → 2,850 Hz) like living lungs.
Overdrive Grit & Pink-Noise Runoff
Sudden summer cloudbursts wash sediment into the brook (spiking past 1,000 NTU), driving a WaveShaperNode soft-clipper and stereo bursts of bandpass-filtered pink noise.
5-Year Berkshire Downs Chalk Catchment Triad (2019–2024)
Three co-located hydrological horizons demonstrating how erratic daily rainstorms buffer through a chalk stream and slowly recharge a deep subterranean aquifer over months.
How It Sounds · Mode 03 Mapping Legend
Erratic High-Hat & Pluck Arpeggios
Surface precipitation triggers rapid, jittered high-passed noise hi-hats and D-Dorian crystalline sine plucks while releasing visual vadose percolation droplets downward.
Mid-Range Polyrhythmic Sequence
Bucklebury river level drives a 5-against-3 melodic FM-bell pattern whose note density and register climb during winter baseflow surges.
Microtonal Sub-Bass Drone
Beenham’s deep groundwater table glides unquantized across 380 microtonal cents (36.7 Hz → 45.7 Hz) over seasonal recharge cycles—turning multi-month hydrogeology into tectonic sub-bass.
Flow-Regime Thresholds & Anomaly Percussion · River Trent at Colwick
Compares 15-minute winter stage and discharge against calibrated normalFlow, highFlow, and floodFlow thresholds—escalating polyrhythms and clock tempo upon breach.
How It Sounds · Mode 04 Mapping Legend
Minimalist Pulse
While river level stays within channel norms, a calm damped membrane heartbeat and dark A1 sub-drone mark time steadily at 1.00× speed.
3:2 Tuned Toms & Snare Wire
Crossing the amber highFlow threshold accelerates playback to 1.28× and unlocks syncopated 3-against-2 stereo tuned toms and crisp snare-wire rim hits.
Urgent 1.58× Polyrhythm & Metallic Chimes
Breaching the crimson floodFlow warning line escalates transport urgency to 1.58×, layering dense Euclidean snare/tom patterns with stereo inharmonic tubular-bell warning chimes.
