Globally, water is the most potent agent of soil erosion. Its potency at room temperature depends on the flow energy. Water induced soil erosion involve breakdown, and transport of broken-down soil aggregates from place of origin to where the displaced particles are deposited, thus stagnant water has very low erosive potentials. Currently, one of the major sources of colossal plagues in Agbor metropolis is soil degradation through soil erosion. Prominence of soil erosion in the metropolis is attributable to high infiltration density, severe rainfalls and long steep topography. This paper examines infiltrations, severe rainfall, topography and urbanization effects on soil erosion, and Orogodo River sustenance in Agbor metropolis. The metropolis mean annual precipitation (1787 mm) was estimated from Delta State annual rainfall data (2005‒2015). Curve number method and Pythagoras theorem apply to estimate the metropolis runoff volume and topography gradient. Newton’s laws of motion apply to estimate runoff acceleration, velocity, force, kinetic energy, and momentum. Volume of sediment deposits in Orogodo River for 28 years (1998−2026) was estimated using the rational method. Research findings reveal Agbor metropolis runoff potentials: flow volume, velocity, acceleration, kinetic energy, force, and momentum is [(779580863.3) m3, (2.5) m/s, (0.026) m/s2, (2.43619E+12) J, (20269102449) N and (3.82964E+13) kgms-1]. Outstanding runoff potentials and unethical waste management aggravate soil erosion, while debris transport downslope is fast sinking Orogodo River. Residents should establish samba and channel courtyard runoffs to it, adopt ethical waste management and provide drainage systems with concrete slab covers to prevent waste deposition into it.
