INTERPRETATION OF CURRENT AND TIDAL PATTERN AT SELANGOR RIVER, KUALA SELANGOR

Abstract. Tidal data has been used to determine long-term water level alterations. Tides are high-powered and notoriously hard ascertain. analysis prediction need substantial study with the requisite approaches, techniques, tools in conjunction weather parameters natural calamities. TOtal TIde Solution (TOTIS) software, which is rooted harmonic analysis, one of most often software Malaysia. This aims interpret current circulation tidal pattern at Selangor River, Kuala Selangor, Darul Ehsan. A period one-month retrieved via Valeport 740 Tide Gauge from tide gauge station, whereas Current Meter 105, analysed. The latest updated for station utilised based on availability data. Therefore, tides predicted using 33 resolved constituents two years, starting January 2021 until December 2022. generates constituents, then prediction. Root Mean Square Error (RMSE) datum offset evaluate software's output. It signifies that TOTIS trustworthy reliable terms accuracy. highest river records high speed occur during phenomenon. output magnitude derived satisfactorily precision. aids monitoring analyse an appropriate method prevent or reduce additional erosion.
