Runoff prediction of urban stream based on the discharge of pump stations using improved multi-layer perceptron applying new optimizers combined with a harmony search

•An improved multi-layer perceptron using new optimizers combined with a meta-heuristic optimization algorithm (IMLP) was developed.•Runoff Inflow was predicted based on the rainfall and discharge of pump stations using IMLP.•Normalization and correlation analysis was applied to conduct data pre-pro...
